What version of Firefox am I using?

You can find out which version you are using in the About Mozilla Firefox window:

1. The first thing you will want to do is open up your Firefox browser.
2. At the the top of the Firefox window, click "Help" and select "About Mozilla Firefox".
3. The About Mozilla Firefox window will appear. Your version number is listed underneath the Firefox name.

This is all you need to do to find out what version of the Firefox web browser you are currently running!

Note: Latest versions of Firefox are designed to automatically check for updates and download
the latest versions of the software as needed.
